Question

Which of the following ordered pairs is not a solution to the inequality y > -2x + 1?

(0, 6)

(0, 2)

(-1, 9)

(1, -3)

Answer 1

Take the inequality y > -2x + 1 and start plugging your points into
y > -2x + 1 and solve. I will do one for you.
(0, 2)
y > -2x + 1
2 > -2(0) + 1
2 > 0 + 1
2 > 1

2 is greater than 1 so this is true. Since it is true it is a solution. Now do the rest like this until you find one that is Not a solution.
